CALIBRATION

- Pressure readings and the calculated volume for the reference and sample cells are shown in Table 5 (below).

- Mean reference cell volume was calculated as 90.867 cm3

- Mean sample cell volume was calculated as 149.068

- Since the reference cell volume and the sample cell volume were within the defined tolerances (90.953 ± 1.0 cm3 for the reference cell volume and 149.225 ± 1.0 cm3 for the sample cell volume), the gas comparison pycnometer was considered acceptable for use.
